This invention relatesto'certain new and useful Improvements in dences for feeding 4 materials into glass furnaces and. has for its bodying-novel operatrngflev'ices for the gate primary object to provide a portable carriageembod ing' a multiple hopper construction wit the carriage movable across a battery of furnace door openings with the device constructed in a manner to permit operation thereof and the feeding of batteryof furnaces by a single operator.

Another object of the invention isto provide a device for feeding materials into glass furnaces in the form of a portable carriage wherein the carriage is provided with a plurality of separate hoppers with an independentlyv operable gate valve for each hopper with all of the hoppers selectively operated by a single person and further enivalves.

Astill further object of the invention is to provide a device of the character above set forth wherein a ladle or conveying bucket having a universal connection with a turn-table construction is capable of being disposed beneath the outlet mouth of the spaced hoppers to receive material therefrom for discharge or delivery intov the glass furnace.

\Vith the above and other objects i view that will become apparent as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed. i

In the drawings, wherein like reference characters designate corresponding parts throughout the several views,

Figureo is a detail sectional view taken on line 55 of Fig. 1,-

Figure -6 is a detail-sectional view taken on line 6 6 of Fig.1, and

Figure 7 is-a (plan view of an operating nace doors.

The. device-for feeding the material into the glass. furnace is in the form of a carriage mounted upon track rails 1 that are; supported upon the flooring or base 2 forfwardly of and parallel with the front wall 3 ofa battery of furnacesthathave en trance openings 4 1n s'aid'front walls 'as clearly shown in Fig. a, the cpenings by the doors 5 shown in F' I As shown in Fig. 3, "eembodies a base structure including lor :udinal side bars 6 and end cross bars '2" supporting platform 8, bolsters 9 depending therefrom supporting cross? axles 1O carry tracl: wheels 11 upon the opposite ends thereof as shown in Fig. 4. Corner posts 12' project perpendicularly from th platform 8 and support a rectangular f i their upper ends that comprises side bars '13'andend structure providing a support for the multiple 'ho pper. arrangement disposed above the 'platform 8. The upper rectangular frameic' $9 braced by the diagonal bars 15.

The hopper being supported upon and; suitablysecured to ,the' upper rectangular frame embodies upper downwardly converging side walls 16 and downwardly con- Q5 verging end walls 17 having a pair of spaced transverse partition bars 18 and 19 f disposed above the rectangular frame. The transverse partition bar 18 and the adjacent end wall 17 provides one hopper embodying 100 dowi'iwardly converging bottom well sec? tions 20 and 21 with an outletopening 22 at the lower end of the bottom wall 2lthat tition wall 19 and the adjacent .end wall 17 is of similar construction and the opening 22 in the wall 21 thereofis'likewisej closed by a sliding gate valve 23. The middle compartment between the transverse partition'walls 18 and-19 embodies down-' wardly converging walls 24121116; 25Twith' a lmPPeY v .andrm,

.- section 21 into side compartments with an outlet opening 27 in eac of the side compartments at the lower ends of the hopper wall that are closed by sliding gate valves 28 as.

shown in Fi 1. The outlet "openings for the interme iate hoppers are located at one side of the carriage while the outlet openings for the end hoppers aredisposed lgs. rand The sev+ intermediatethe o positesides of the cari bearings 46 interposed therebetween, a cene, tral shaft 48 extending thru the disk 46 and ,turn-table 47. A horizontal arm 49 jour- 5.1;naled on the shaft 48 and fixed to the turn- {liable 47 has a depending counterbalancing weight 50 at one end thereof, while the ria e as shown in em hoppers are adaptedg t'mcolitai'n mater l to'be sent to the furnace ture of glass, such as sand," daash, lime and culle't or the like.

As shownin Fig. l, the sliding '28 for the intermediate hoppers have guides 29 associated with the opposite side edges thereof and the operating means for the gate valves 28 include the provision of a bell crank lever 30 pivoted to the bottom wall sections 25 with link connections 31 between the end of one leg of the bell crank lever and the upper end of the gate valve. The

. other leg of the bell crank lever is provided with a notch 32 to receive the hook end 33 of the operating rod 34 shown in Fig. 7 that may alsobe employed -for opening the faruses doors 5. Theoperating means for the gate valves 23 closing the outlet opening 22 of the end hoppers is shown more clearly. in Figs. 1, 4

frame has the free end of and 5 and include the bellcrank lever 35 pivotally su ported u on the bottom wall the end opper and having a .link connection 36 with the up er end of the gate valve 23. A bell cra lever 37 pivotally supported 'beneath one of the upper side bars 13 of the upper rectangular one of its legs pivotally attached as at 38 to a link 39, the other end of which is pivotally connected as at 40 to the other leg of the bell, crank 35. A forked bracket 41 fixed to the side bar 13 above-the 'bell crank lever 37 has an arm 42 sting hand .50

sting means for W is transmitted to the bell crank 35 for raising and lowering the sliding gate valve 23. k In view of the relative positions pivotally mounted at one end between the outer forked end of said bracket while an operating lever 43 is pivoted at one end to the outer free end of the arm 42. A link 44 extends between the outer leg of the bell crank lever 37 and the operating lever 43 and when said lever 43 is shifted, movement levers 37 and attire pivot points for the arm 42 and the link 44, said arm and link with the oper= le 43 carried thereby may be a position adjacent thecarriage device is out of use. The opereach of the sliding gate valves 23 associated with the end hoppers is shifted to when the identical and repetition of description is thought unnecessary.

gate valves permits the ladle to be disposed beneath each of the outlet openings of the hoppers and to beLprOjectedthrOugh the door openvings 4 in :the glass furnace. This construction embodies supporting legs or standards 45 shown more clearly in Figs. 1 and 3 having a disk head 46 upon which'a rotatable turn-table 47 is supported with ball other end of the arm 49 is provided with a 1 universal mounting for the ladle handle. A block 51 carries a depending stub shaft 52 journaled in the outer end of the arm 49,

the block carrying a pair of upwardly directed side arms 53 in the upper ends of which side pins 54 carried by a ring 55 are journaled. The bucket ladle 56 is carried by a relatively lon handle 57 that is rotatably mounted in the ring 55 against longi tudinal movement therein. The ladle. 56 is so disposed relative to the bearing for the handle 57 so that when the arm 49 is shifted upon the turn-table by manipulating the handle 57,,the ladle'may be disposed beneath any one of the outlets for the hoppers.

From the above detail descri tion of the invention, it is believed that t e construotion and operation thereof will at once be apparent, it being noted that the carriage is movable over the 'itraok 1 forwardly of a battery of glass furnaces while a 'single person can manipulate the'ladle 56 to dis pose the same beneath the desired hopper and operate the sliding gate valve of the chosen hopper.- The'gat-e valves 23 for the end hoppers are'operated by the lever 43 which causes shifting movement of the bell crank levers 37 and 35 for raising and lowering the gate valve while the gate valves 28; associated with the intermediate hoppers may be operated by the rod 3 shown in Fig. 7, which rod is also employed for opening and closing the furnace doors 5. WVith a device of this character wherein a single operator may charge the furnace with the desired material, a great saving in labor is effected as well as reducing the cost of manufacture.

While there is herein shown and described the preferred embodiment of the present in vention, it is, nevertheless, to be understood that minor changes may he madet-herein without departing from the spirit and scope of the invention as claimed.
